What they say
"I think it's the best IF language I've ever seen - and I *am* a programmer."
Andrew Heale
"If I was to write a new text adventure I wouldn't bother with any other authoring system. Alan is just that much easier."
Felix Pleșoianu
"I gotta say, I love it!"
Robert DeFord
"Alan definitely met my expectations. I was able to create two pretty large, complex games with no prior programming experience."
Byron Campbell
"I-F languages are like vehicles ... using Alan is like driving a zippy, easy-handling little electric town car -- it's often all you need to take you where you want to go."
Lelah Conrad
"Man, I just finished programming a little game with Alan, and let me tell you ALAN RULES!! It's so simple, *I* can program with it."
